For writing official packages there is a packaging user guide.
The setup script is the centre of all activity in building, distributing, and installing modules using the Distutils. It's purpose is the correct installation of the software.
If all you want to do is distribute a module called foo, contained in a file foo.py, then your setup script can be as simple as this:
from distutils.core import setup setup(name='foo', version='1.0', py_modules=['foo'], )
To create a source distribution for this module, you would create a setup script, setup.py, containing the above code, and run this command from a terminal:
python setup.py sdist
sdist will create an archive file (e.g., tarball on Unix, ZIP file on Windows) containing your setup script setup.py, and your module foo.py. The archive file will be named foo-1.0.tar.gz (or .zip), and will unpack into a directory foo-1.0.
If an end-user wishes to install your foo module, all she has to do is download foo-1.0.tar.gz (or .zip), unpack it, and—from the foo-1.0 directory—run
python setup.py install
Command line scripts inside python packages are common. You can organise your package in such a way that when a user installs the package, the script will be available on their path.
If you had the
greetings package which had the command line script
greetings/ greetings/ __init__.py hello_world.py
You could run that script by running:
However if you would like to run it like so:
You can achieve this by adding
scripts to your
setup.py like this:
from setuptools import setup setup( name='greetings', scripts=['hello_world.py'] )
When you install the greetings package now,
hello_world.py will be added to your path.
Another possibility would be to add an entry point:
This way you just have to run it like:
setuptools_scm is an officially-blessed package that can use Git or Mercurial metadata to determine the version number of your package, and find Python packages and package data to include in it.
from setuptools import setup, find_packages setup( setup_requires=['setuptools_scm'], use_scm_version=True, packages=find_packages(), include_package_data=True, )
This example uses both features; to only use SCM metadata for the version, replace the call to
find_packages() with your manual package list, or to only use the package finder, remove
As seen in previous examples, basic use of this script is:
python setup.py install
But there is even more options, like installing the package and have the possibility to change the code and test it without having to re-install it. This is done using:
python setup.py develop
If you want to perform specific actions like compiling a Sphinx documentation or building fortran code, you can create your own option like this:
cmdclasses = dict() class BuildSphinx(Command): """Build Sphinx documentation.""" description = 'Build Sphinx documentation' user_options =  def initialize_options(self): pass def finalize_options(self): pass def run(self): import sphinx sphinx.build_main(['setup.py', '-b', 'html', './doc', './doc/_build/html']) sphinx.build_main(['setup.py', '-b', 'man', './doc', './doc/_build/man']) cmdclasses['build_sphinx'] = BuildSphinx setup( ... cmdclass=cmdclasses, )
finalize_options will be executed before and after the
run function as their names suggests it.
After that, you will be able to call your option:
python setup.py build_sphinx
